Jonathan Wakely f4130a3eb5 libstdc++: Deprecate std::unexpected and handler functions
These functions have been deprecated since C++11, and were removed in
C++17. The proposal P0323 wants to reuse the name std::unexpected for a
class template, so we will need to stop defining the current function
for C++23 anyway.

This marks them as deprecated for C++11 and up, to warn users they won't
continue to be available. It disables them for C++17 and up, unless the
_GLIBCXX_USE_DEPRECATED macro is defined.

The <unwind-cxx.h> header uses std::unexpected_handler in the public
API, but since that type is the same as std::terminate_handler we can
just use that instead, to avoid warnings about it being deprecated.

libstdc++-v3/ChangeLog:

	* doc/xml/manual/evolution.xml: Document deprecations.
	* doc/html/*: Regenerate.
	* libsupc++/exception (unexpected_handler, unexpected)
	(get_unexpected, set_unexpected): Add deprecated attribute.

Christophe Lyon 5d727a4b20 [ARM/FDPIC v6 06/24] [ARM] FDPIC: Add support for c++ exceptions
The main difference with existing support is that function addresses
are function descriptor addresses instead. This means that all code
dealing with function pointers now has to cope with function
descriptors instead.

For the same reason, Linux kernel helpers can no longer be called by
dereferencing their address, so we implement wrappers that directly
call the kernel helpers.

When restoring a function address, we also have to restore the FDPIC
register value (r9).
